1. A digital image acquisition device, comprising:

  • an imaging optic and detector for acquiring digital images including one or more preview images and a main image;

    a processor;

    a face detector to analyze the one or more preview images to ascertain information relating to candidate face regions therein, the face detector including a search module for detecting candidate face regions;

    a face tracking module for predicting and confirming candidate face regions;

    an image acquisition chain for image processing to generate a sub-sample resolution version of the main image, including a reduced resolution version of an approximately same scene as the main image;

    a first speed-optimized red-eye filter to produce a first set of candidate red-eye regions in the sub-sample resolution version of the main image based on the candidate face region information provided by the face detector;

    a display to show a first speed-optimized red eye filtered acquired image thereon; and

    a second analysis-optimized red-eye filter configured to be activated after display of said first speed-optimized corrected acquired image on said display, said second filter being activated upon initiation of an image playback mode, said second analysis-optimized red-eye filter being configured to produce, with enhanced accuracy of red-eye detection and/or higher quality of image correction than the first filter, a second set of candidate red-eye regions for viewing at a higher resolution than the first speed-optimized red eye filtered acquired image shown on said display.
